I have an HP laptop ENVY m6, with 8 Gb of RAM and a 750 Gb HDD. It came with windows 8 pre-installed and I installed Ubuntu 13.04. It worked fine but after upgrading Ubuntu to 13.10 my laptop fails to boot showing this error:

error:file /boot/grub/i386-pc/normal.mod  not found 
Entering rescue mode 
grub rescue>

I tried to fix this error with BootRepair without any luck. I got this BootInfo. Help me please fixing this problem, I have struggled consecutively for four days.

Note: in my BIOS settings I have disabled secure boot, but legacy support is enabled.
